What customers say
This foam set is highly praised for dramatically improving spacebar acoustics. Users consistently report that it eliminates distracting hollowness and resonance, transforming the sound into a satisfying, deep thock or solid thud. This modification significantly enhances the overall typing experience. Reviewers appreciate the precision cut and quality material, noting the foam fits snugly without interfering with switches or stems. The set offers excellent value, providing necessary internal dampening, especially for users with thick PBT keycaps. It is widely considered an essential, inexpensive upgrade for achieving a premium, uniform keyboard sound.
Know before you buy
These foams are specifically engineered for the internal dimensions of CRP Cherry profile keycaps. While they may physically fit under other Cherry profile spacebars, the acoustic results and fitment may vary.
No, these are designed exclusively for PCB-mount stabilizers. They will not fit correctly with plate-mount or Costar stabilizer systems.
The 6mm foam is designed to fill the hollow cavity of the spacebar to eliminate resonance. It provides a more solid, dampened sound profile without significantly altering the travel distance or bottom-out feel.
The pack contains three individual foams for 6.25u spacebars and three individual foams for 7u spacebars, totaling six pieces of foam.
No adhesive is required. The foam is cut to a precise friction-fit size that stays securely inside the spacebar cavity once installed.
